Report an issue with this species
Amelanchier alnifolia is a versatile shrub or small tree known for its attractive, showy white flowers in early spring, providing nectar for pollinators. It produces edible, reddish-purple berries in summer, enjoyed by birds and wildlife. This species is adaptable to various soil types, but gardeners should be aware of its susceptibility to powdery mildew and tendency to produce root suckers, which can lead to a dense, clumping habit if not managed.
